Probably not the most sensible thing I've done, going down into the underground reserve transmitter block. As with any derelict or old military structure you should take great care - sensible guidelines can be found on the Derelict Places website. Any site I've posted on this blog should not be assumed safe! I came across the entrance by pure chance and could not resist a look. Cannot believe it has not been properly sealed.
Anyway, climbing down, met with an unpleasant smell and a swarm of flies (hanging around the many dead rabbits that had fallen down!). As the pics shows, nothing remains in the underground chamber except what I assume is the part of the ventilation unit. Interestingly, the surface air shafts seem to be quite a distance away from the space I visualised the underground bunker to occupy. There were no other doors inside that I saw, so I do not know if the sunken reserve transmitter block actually occupies a wider area than I explored. A second sunken bunker can be found further south, but thankfully no access to this!
